摘要： An in-line suspended power sensor coupling configuration situated within a high frequency transmission line housing that allows forward, reverse, and sampling voltage elements to all be produced simultaneously on one double sided printed circuit board (PCB). The power sensor coupling allows for calibrated coupling responses across a much wider frequency range with a single PCB assembly, as opposed to the need to cover equivalently sized frequency ranges with multiple individually fabricated coupling element assemblies.

摘要： Embodiments of the invention include an electromagnetic waveguide and methods of forming the electromagnetic waveguide. In an embodiment the electromagnetic waveguide includes a first spacer and a second spacer. In an embodiment, the first and second spacer each have a reentrant profile. The electromagnetic waveguide may also include a conductive body formed between in the first and second spacer, and a void formed within the conductive body. In an additional embodiment, the electromagnetic waveguide may include a first spacer and a second spacer. Additionally, the electromagnetic waveguide may include a first portion of a conductive body formed along sidewalls of the first and second spacer and a second portion of the conductive body formed between an upper portion of the first portion of the conductive body. In an embodiment, the first portion of the conductive body and the second portion of the conductive body define a void through the electromagnetic waveguide.

摘要： Disclosed herein are implementations of devices and methods for side mounting of microelectromechanical systems (MEMS) transducers on tapered horn antennae. A hole is made in a sidewall of a tapered horn antenna, where the hole is substantially cylindrical, tapered and the like. In an implementation, an internal port opening of a MEMS microphone is aligned with the hole and attached to the sidewall of the tapered horn antenna. In an implementation, the hole is tapered with a diameter at one end, either the same or slightly larger than the diameter of the port opening of the MEMS microphone and a larger diameter at another end of the hole. In an implementation, a tube is used to connect the internal port opening of the MEMS antenna to the hole in the tapered horn antenna. In an implementation, the tapered horn antenna may have multiple holes, each having its respective MEMS transducer.

摘要： A detection device includes a substrate on which a connector connected to a transmission line for microwaves, a detection circuit configured to convert the microwaves inputted from the transmission line via the connector to a detection value indicating power of the microwaves, and an output port configured to output the detection value obtained by the detection circuit are disposed. The detection device further includes a housing that has a first opening and a second opening and accommodates the substrate in a state where the connector is inserted into the first opening and the output port is inserted into the second opening. The detection device further includes a first sealing member provided at the first opening of the housing to seal a periphery of the connector; and a second sealing member provided at the second opening of the housing to seal a periphery of the output port.

摘要： A waveguide rotary joint includes a first waveguide member comprising a first waveguide portion, and a second waveguide member comprising a second waveguide portion, the second waveguide member rotatably connected via a curved circumferential path to the first waveguide member, wherein the second waveguide portion is adjacent to the first waveguide portion to define a first split rectangular waveguide. A first waveguide input/output port is communicatively coupled to the first waveguide portion, and a second waveguide input/output port is communicatively coupled to the second waveguide portion. Relative rotation between the first waveguide member and the second waveguide member changes an angular length of the first waveguide connecting the first waveguide input/output port to the second waveguide input/output port.

摘要： A power distribution circuit includes a first portion, a second portion, a third portion, an isolation element, a first transmission sub-circuit and a second transmission sub-circuit. The first portion, the second portion, and the third portion are coupled to respective external components. The isolation element is coupled between the second portion and the third portion. The first transmission sub-circuit is set on one side of the isolation element, and is coupled between the first portion and the second portion. The second transmission sub-circuit is set on the other side of the isolation element, and is coupled between the first portion and the third portion. The first transmission sub-circuit and the second transmission sub-circuit are symmetrically set on both sides of the isolation element.

摘要： A mounting substrate includes a circuit board and a coupler. The circuit board has a mounting surface on which a microwave integrated circuit element is to be mounted, the microwave integrated circuit element having a plurality of terminals including first and second antenna I/O terminals. The coupler connects the first and second antenna I/O terminals to a waveguide device. The coupler includes: a first electrical conductor portion to be connected to the first antenna I/O terminal; a second electrical conductor portion to be connected to the second antenna I/O terminal; and an elongated gap in which an end face of the first electrical conductor portion and an end face of the second electrical conductor portion oppose each other. The elongated gap has a narrow portion at which the distance between the end face of the first electrical conductor portion and the end face of the second electrical conductor portion is locally decreased. The coupler couples an electromagnetic field being produced at the narrow portion to a waveguide in the waveguide device.

摘要： A substrate is used as one tube wall of a hollow waveguide, the substrate including a strip line wired in an inner layer, a first ground surface formed on a front surface, and a second ground surface formed on a part of a back surface. As a result of such a configuration, a waveguide strip line transducer having the same dimension as the external dimension of the hollow waveguide can be obtained.
